2xGTX280 Graphics cards in SLI (different Brands)

So i have one Asus GTX280 and im thinking of getting another GTX280 to set it up in SLI probably Gigabyte or something

The question is will 2 same GTX280's run in SLI if they are different brands? same clock speed, same memory, will it work?

and If they do give me some links please

yes, as long as the cards are the same model, they will work flawlessly together, you can mix and match different brands, they dont even need to be the same clock speeds, just as long as they are the same model, if they weren't the same model, then vista will allocate one as a physics card

yep.....you wont have a problem

its even possible with different clock speeds, but they'll always default to the lowest speed.

i think you can even run a 192 & a 216 SP revision GTX260 in SLI, but again i think it will only utilize 384 SPs rather than 432 SPs

I thought this was also the case guys thanks, wanting to confirm.

I was also thinking about buying something like a GTX260 or 275 for physics or is this overkill for a physX Card?
would I be better getting something like a gts 250 or something even not as good as that?
I have a tri-SLI mobo so I thought I may as well utilise the PCI slots a bit.

if you got the spare cash, then go for it, but im not sure that a 275 will work, that would effectively be quad SLI, I would stick to a single core GPU, the 216 GTX 260's are going quite cheap at the moment

yes its OVERKILL!!!!! , get a low end 9600GT or something it'll cope perfectly well with PhysX

Cheers Archie, Thought I would only need something small neat and tidy, because from reviews Ive seen, 2 - gtx 280's with a 3rd graphics card for physx performs better than 3 - gtx 280's in tri-SLI, whether this is indeed the case i dont know, if it will still improve my graphics performance for 1/3 of the price of getting 3 gtx280's as opposed to 2x 280s + a 9600GT.
Its worth it to make your eyes bleed when you have 16AA + 8AF on 1920x1200 display showing Farcry 2 with every feature maxed out on 70FPS.
And so it was written that PS3's graphics never had anything on PC

Why not just drop a 100$ and get a good physX card, a whole lot cheaper. Preforms pretty good, low cost also.

The reason why why I wouldnt, is if one of my mates had a display adapter problem on their pc, I could quickly transfer my new low end graphics card (used for physX on my pc) to theirs and use it as a graphics card, just as cheap, does the job, and I can use it to help others too.

Why would you get a 280? It's virtually obsolete. DirectX 11 will be here by January, and if you can't wait a single GTX 295 is enough or a pair of 4890's in crossfire.

Let's think about this logically. a GTX 295 is 2x GTX260's in SLI on one card. I already have a GTX280. Im thinking of getting another GTX280 for the sake of it. if I were to get a GTX295 it would be a waste of money because it wouldnt offer the performance of 2xGTX280's in SLI. and I would be able to buy one GTX280 for less than half the price of the 295 giving me better performance for price.

Ive researched it, and there are 4 games coming out with DX11 (with ATI in october releasing its newest cards)

Battleforge (EA) - around September/October 2009
Stalker: Call of Pripyat (GSC) - November 2009
Dirt 2 (Codemasters) - December 2009
Alien vs. Predator - beginning of 2010

AMD confirms DirectX 11 games: Battleforge, Stalker: Call of Pripyat, Dirt 2 and Alien vs. Predator - DirectX 11, AMD, Radeon 5000, Battleforge, Stalker: Call of Pripyat, Dirt 2, Alien Alien vs. Predator - PC Games Hardware

Because Nvidia wont be releasing its DX11 cards until 2010, alot of games developers that have already signed their contracts with Nvidia wont be able to develop their games optimised for Nvidia cards, they will have to delay until Nvidia releases their cards, so Id say we have until end of Q1 next year before we start seeing all the good games come out. In the meantime games will be backwards compatible with DX10 and DX11 will only come into its own with the 2nd gen DX11 High end cards from ATI (but we still havent heard anything about the quiet intel company sporting Larrabee)
